- Fats have the most potential energy of all the biomolecules because they have the most ___________________ atoms associated with ___________________ atoms. Your answer should consist of the first blank word with a comma and a space between them. For example: black, whitearrow_forwardCells can store energy as starches (long polymer forms of carbohydrates, or sugars) and fats. If you isolate the starch stored by a cell, you would find that a lot of the mass of the isolated starch is actually water. However, if you isolate the fat stored by a cell you would find that very little of the mass of the fat is water. Explain this difference based on the structures or properties of the starch and fat moleculesarrow_forwardDescribe two conditions when it is more advantageous to use carbohydrates as a metabolic fuel rather than lipids, and explain why . Why might lipids be more advantageous under the opposite condition?arrow_forward
- Lactose is a disaccharide made of a glucose and a galactose bonded together. Lactose is found in milk yet does not taste sweet because our taste receptors do not sense lactose. Our taste receptors do sense galactose and glucose. How can a mug of warm milk taste sweet, without adding sugar? [Select the best answer.] The activation energy required for the hydrolysis of lactose into glucose and galactose is supplied by heating the milk. The milk proteins are denatured by the heat. The reaction is endergonic so the heat is the energy required for the reaction to occur. The lactose has less free energy than the glucose and galactose.arrow_forwardLet us say that the four major classes of biomolecules (Carbohydrates, Proteins, Nucleic Acids, and Lipids) are in the form of food, which one of the four do you think will give you the most energy? Why?arrow_forwardWhich of the following statements is a lie? Select one: a. Chemical energy is the energy within chemical bonds. Energy is required for bonds to break while energy is released when bonds form. b. Exergonic chemical reactions release more energy than they absorb and the catabolism of the food in an energy bar serves as an example. c. The many forms of energy used up by cells comes from the breakdown of the chemical energy from the food we digest.arrow_forward
- Dixie Bee wanted to make JELL-O shots for her next party, but felt guilty about encouraging her guests to consume alcohol. She tried to compensate for the toxicity of the alcohol by adding pieces of healthy fresh pineapple to the shots, but when she did, the JELL-O never solidified. What happened? Hint: JELL-O is mainly sugar and a gelatinous mixture of proteins.arrow_forwardMatch each type of molecule with its description. _________ chain of amino acids _________ energy carrier _________ glycerol, fatty acids, _________ phosphate _________ chain of nucleotides _________ one or more sugar units a. carbohydrate b. phospholipid c. protein d.

- A molecule of glycogen is formed by linking glucose molecules through this process. The separation of polymers into smaller units makes use of this process. This process does not involve breaking peptide bonds, but it does involve unfolding protein structure. The addition of water to break proteins into amino acids is an example of this process. Dehydration Synthesis Using acids to cook raw fish is an example of this process. This process removes water to link two or more amino acids. Denaturation Breaking DNA into nucleotides involves this process. The change to the color and consistency of an egg during cooking is an example of this process. Monomers are linked together through this process. Hydrolysisarrow_forwardList 3 types of carbohydrates.
